This measures a single qubit in the Pauli-Z basis such that the output result is given by the distribution. The M operation is defined as:
Pr(Zero||ψ ⟩ )= ⟨ ψ|0 ⟩⟨ 0|ψ ⟩
How does the Q# language differ from C#? Here are a few points.
The using statement is different from that of C#. It's used to allocate an array of qubits for processing. Like the using statement in C#, the qubits are released at the end of the using statement. There are no qubits that are used for the entire lifetime of the application.
Q# has a different for loop that is used to iterate through a range. There is no direct equivalent of a C# for loop.
Q#, by default, has all variables as immutable, meaning that once they are assigned, they cannot be changed. There is a ...
